I have a 94 200. Recently it has been hard to start. I can get it going after working at it for like 5 mins when playing with the choke on and off. I checked the reeds and they are good. I also replaced the air screw because that was missing. Still nothing. When it finally does start it runs really rich, most likely from flooding it. A bit more recently after replacing the air screw, it runs sluggish until I get on it and wants to die sometimes when coming to a stop. I have the air screw adjusted to the factory setting. Any suggestions?

the thing is it ran fine, for months. I went on a long ride, parked it for a few hours and it started doing this.

check compression?

i dont a have a compression tester, but i know i can barely turn it over be hand.

So i did pull off the fly wheel cover and noticed that there was fuel/oil mixture in there :/. Next questions, this is most likely the culprit, how hard is that seal to replace? I looked it up on the parts website and it seems to be http://www.kawasakipartshouse.com/oempa ... /crankcase 92049, does that sound right?

does this video look like the right way to replace it? http://www.youtube.com/watch?v=pefRYiaHKqA

Normally if you're going to replace the crank seals you'd split the cases, and replace the bearings as well. Not overly difficult, but it does take your bike down for a bit.

do you have to split the case to replace that seal?

I just posted with the same issue. I found my silencer fiberglass packing was caked so bad with spooge that it was plugging it up. check it too before you go splitting cases.

Hi, see this video before splitting the cases and make sure you don't have the same problem. This is an easy fix compared to changing the crank seals.

Sounds a little to me like the old air screw could have been making it run lean, as we know stock they run very rich and can give the symptoms you describe so the new air screw would have richened the mixture back up. I would suggest going through the jetting guide on here as a starting point. And to state the obvious, use a new plug. Mine takes ages to start with an old plug, I chuck a new one in every few rides.

What about the gas in the flywheel cover? Also it was hard to start after the ride without the airscrew. To be honest i dont believe it even had the air screw in it when I bought it. I have the bike inside and will check the jets to see what size they are being that the bike is new to me as of a couple of months ago.

also why would it just start to be hard to start after a ride? any suggestions?

Plug? Have you got a new plug to try?

yes tried several plugs and no diffrence. Took the car apart today and I have a 155 Main and 48 pilot jet.

So to took the carb apart and found that there was a little sand in it. I cleaned the thoroughly and am going to put it back in and see if that makes a difference.
